Mac os ssh ppk

That’s it, now you’re logged in to the remote machine via SSH.

At this point you have access to any command line functionality on the remote computer, assuming you have privileges to perform the task or execute the command. What you do once you’re connected with SSH is up to you, but as state earlier it’s intended for advanced uses like systems administration, server management, network operations, and other higher level tasks that are generally less relevant to the average computer user.

When you’re finished you can type “exit” to disconnect from the remote machine, or just close the Terminal app to close the ssh client and connection.

* Side note: you can also SSH into your own Mac this way if you juts want to try this out, but there is little point to that since launching Terminal in and of itself grants you direct shell access to the computer to begin with. But, it does offer a means of experimenting with SSH connections if you have never done so before, just use your username @ localhost or 127.0.0.1 for the IP.

By the way if you want to allow someone else to remotely SSH into YOUR Mac, you’d need to setup the native SSH server on your Mac (easy as described here) and then you’d want to add a new user account to the Mac for that person, never share your own login and password with anyone else. Keep in mind if you give someone SSH access to your Mac with an admin account, you are giving them full access to your computer, all files, apps, activity, logs, and everything else, representing complete and total remote access to the computer. The command line has a huge number of commands available and is more powerful than the familiar graphical interface (GUI) we all know and love, so you probably do not want to allow for this randomly. Anything you can do at the command line can be done through ssh, assuming appropriate user privileges – this is why it’s so widely used for systems administration and by advanced users, and much less relevant to neophytes and the less technically inclined. If you want to give someone remote access for troubleshooting purposes and you’re a novice, a better approach is to use screen sharing instead.

Как жить в Mac OS без Putty? Аналоги.

В Windows проблема подключения по SSH полностью решалась с помощью всем известной утилиты PuTTY. Пользователи Linux тоже не остаются в обиде, и на их платформе есть это приложение. Странно, но для Мак платформы разработчики PuTTY не сделали. Пришлось искать варианты.

Установка PuTTY на Mac OS

Во первых, для поклонников этой программы, есть вариант установки самой PuTTY на Мак, с помощью систем портирования Linux программ на Mac OS (Homebrew,Xcode, XQuartz). Подробно о такой установке написано в этой статье.

Аналоги PuTTY на Мак

Кроме этого есть аналоги программы для Мака.

Правда его цена немного «кусается». Программа предлагается по цене 80$! С сайта разработчика можно скачать Trial версию на 30 дней.

Apple Store при запросе «ssh client» показывает программу vSSH . Цена программы уже более гуманная — 169 рублей.

Использование терминала для SSH соединения

Но самым популярным в Mac OS является использование консольного терминала.

Тут рекомендуется вместо стандартного терминала платформы использовать приложение iTerm2 — пожалуй, самый популярный терминал для Мак Оси доступный бесплатно.

Для инициации SSH соединения используется команда:

ssh 192.168.1.1 -l user

В принципе, для большинства задач этого хватает.
Выбор за вами!

How to Enable SSH on a Mac from the Command Line

All modern Macs running macOS or Mac OS X come with SSH pre-installed by default, but the SSH (Secure Shell) daemon is also disabled by default. Advanced Mac users may appreciate knowing the ability to enable SSH and disable SSH are both available entirely from the command line of Mac OS, allowing for a simple way to allow or disallow remote connections into a computer. There’s no kext loading, downloads, or compiling necessary, to turn on SSH from the Terminal on any Mac you simply have to execute a system setup command, as we’ll show in this tutorial.

A quick side note; this guide applies to all versions of macOS and Mac OS X, but is really aimed at more advanced users who spend a lot of time in the Terminal. If you want to toggle SSH off and on and avoid the command line, you can do so by enabling Remote Login in the Sharing preference panel on a Mac, or stop the server by leaving it unchecked. If you do not regularly use ssh, there is no reason to enable the ssh server on a Mac.

How to Check if SSH Remote Login is Enabled in Mac OS via Terminal

Want to check the current status of SSH on a Mac? Using the systemsetup command string we can quickly determine if SSH and Remote Login is currently enabled on any Mac:

sudo systemsetup -getremotelogin

If remote login and SSH is currently enabled, the command and report will say “Remote Login: On” whereas if SSH is disabled and in the default macOS state, it will say “Remote Login: Off”.

Enable SSH on Mac from the Command Line with systemsetup

To quickly turn on SSH server and allow incoming ssh connections to the current Mac, use the -setremotelogin flag with systemsetup like so:

sudo systemsetup -setremotelogin on

sudo is necessary because the systemsetup command requires administrator privileges, just like when you enable Remote Login from the Sharing preferences on a Mac to enable the secure shell servers.

There is no confirmation or message that Remote Login and SSH has been enabled, but you can use the aforementioned -getmorelogin flag to check and verify that SSH server is indeed now running. And yes, using -setremotelogin applies to enabling both ssh and sftp servers on the Mac.

Once ssh has been enabled, any user account or person who has a login on the current Mac can access it remotely using the ssh command aimed at the Macs IP address like so:

Once connected, the user will have remote access to the computer via the command line, and if they have an admin account or admin password, they would have full remote administration access as well.

Turn Off SSH on Mac OS with systemsetup

If you want to disable SSH servers from the command line and thereby prevent remote connections, simply switch ‘on’ to ‘off’ with the -setremotelogin flag of systemsetup like so:

sudo systemsetup -setremotelogin off

Again, sudo is necessary to toggle SSH off and disable the ssh and sftp servers.

When you successfully execute the command, you will be asked: “Do you really want to turn remote login off? If you do, you will lose this connection and can only turn it back on locally at the server (yes/no)?” so type “yes” to confirm, which will disable SSH and also disconnect any active SSH connections to the Mac in question. If you want to avoid having to type yes/no, perhaps for inclusion in a setup script or otherwise, you can use the -f flag to circumvent the question like so:

sudo systemsetup -f -setremotelogin off

Similarly, you can also use -f to skip any prompts in regards to enabling SSH as well.

systemsetup -f -setremotelogin on

Do note that whether you turn SSH off or enable SSH from the command line, the Remote Login system preference panel setting in Mac OS X GUI will be adjusted to reflect the change accordingly as well.
